To all whom it may concern:

Be it known that 1, JAMES F. Srnns, a citi- Zen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Ventilators for Windows, of which the following is a specification, rel'erence being had. therein to the accompanying drawing.

My invention relates to improvements in ventilators forwindows, and has-particular relation to the use oi such structures in. display windows 01 stores and at other points where liability of sweating and freezing is present.

One of the objects of my invention is the provision of a ventilator lor controlling the temperature on the inner side oi a window, of such construction as will enable it to be readily and quickly manipulated from the interior oi the window to control the quantity of air adi'nitted.

A further object is the provision of a device of this character which requires a minimum number of parts, each of which is relatively light in weight, the manner elf mount ing the parts providing for stability, thereby providing a construction which can be manufactured with a minimum of cost, which will be neat and attractive in appearance, durable in construction, simple and eiiicient in operation, and which can be readily applied to position.

To these and other cin s, the nature of which will be readily understood as the invention is hereinafterdisclosed, said invention consists in the improved construction and combination of parts hereinafter fully de scribed, illustrated in the accompanying drawings, and particularly pointed out in the appended claims.

in the drawings, in which similar reference characters indicate similar parts in each of the views,-Figure 1 is a vertical sectional view of a wii'i(lov-'-ii'aine provided with ventilators in accordance with my invention. Fig. 2 is a horizontal sectional view of portion of an angular window-frame, each the side portions of the frame heing showi'i as provided with an independent ventilator. Fig. 3 is a view of the inner side of a window frame, the exposed partsof the ventilator being shown in front elevation.

The structure of the ventilator consists two guides 4:, and the slides 6, together suitable protecting members or slee es l a, l l

These parts are applied, to suitable parts of the-windowframe, such as the rail 1, throu h which extend a plurality of openings 2, t e outer'ends otwhich receive the protecting rnemhers 3. The specific construction and relative arrangement of that portion oi the ventilator located on the inner side of the Window, is as follows: i, 4, designate two guides each of which is angular L-shaped) in cross-section,

one oi the angle sides (the longer) being se cured to the rail 1, the plane of said side be ing at right angles to the rail, while the other angle side is spaced from andextends in. a plane parallel with said face, the angle sides of the opposing guides which are parallel with. the, face of the the plane of the faceof l 7U rail-face being in alinement with each other, I

while the other angle sides extend in plane's p arallel with each other, this construction provicing a slide-way between the rail face and the inner faces of the alined angle sides of the guides. 6 designates the slide which is mounted in said slide-way, said slide having its end or ends up, at '7, to form handles or for moving the slide slideway. Each slide is provided with a plurality of openings 8, corresponding in number and size to the openings 2 of the rail 1, and so positioned relatively to each other as to register with the openings 2 when the maximum quantity of air is tobe permitted to enter the window through the ventilator The guides 4e are secured in position by screws 5}, or other suitable securingmeans,

said screws e riding through the parallel angle sides of: the guides and therefore at direct right m les 'to the direction of any pressi w ii'iigiit he planted on the slide 'hi'lIOilgii the openin 's 2, when the slide is closed, i'ience, a posh vhoiding means for the guides provided, being such as to elimiwithin the nate the necessity ior the oi" heavy and cumbersome form oi guide. find the fact uides are indepe snt or separate since the each other, may he n m. a;

The particular form of the guides is also advantageous inasmuch as they may be readily secured in position in such manner that the sides of the guides within which the screws are located may be protected by suitable means, such for instance as a strip 15, as shown in. Fig. 1, while the opposite angle side will be seated in a recess formed in the under face of the rail, thereby practically cepting from the inside of the window and then only by removing a portion of the frame-work.

Having thus described my I claim as new is 1. The combination with a window frame a plurality of openings extending theret rough, of independent spaced guides carried by the frame in opposed-relation, each guide being angular in cross-section, said guides havin one of the angle sides extendin in paialle ism, said angle-sides being parallel with the axis of t e openings and disposed relatively to said openings in such manner as to present the inner ends of the openings between and spaced from said the adjacent angle sides bein and spaced from the face of the invention, what in alinement extending therethrough, of preventing access to the screws exare shown as applied at the thereby per a circulation throw 1 the ventilators on the inner side of to prevent the latter sweating or becoming frosted, the temperaof the pane being aphere the display window is in the-form of an extension, the window being closed by an inof sweating or frostand I therefore, in

cross-section to its guide, and eachguide having a or tion ex-v tending within the plane frame, said portions being cpncealed by such frame and from the inner ends of said openings to provide a slide-way, means for.securing the parallel angle sides to ,the frame, and a slide mounted indsaid slide-way, said slide having a plurality, of openings corresponding in number and position to the openings of the frame. I

2. In a windowframe, the combination with a rail having a plurality of openings independent spaced guides carried by said rail, said guides extending over the inner face of the rail on opposite sides of and s aced from the rail openings, each guide lieing L-shaped in cross-section, and having one of its sides extending in a plahe at right angles to the face of the rail, said side extending in a plane parallel with the axis of the rail openings, the other side of the guide being spaced from and extending parallel with said rail face and the inner ends of the openings, means for securing the first-named side of the guide to the rail, and a slide mounted between the rail face and the opposing faces of the 'uides, said slide having openings corresponding in nuinber and position to the openings in the rar 3. The combination with a window frame having ventilating openings extending therethroug of a slide movable over said openings, said slide having openings corresponding in number and position to the ventilating openings, and independent means located on opposite sides of and inner ends of said openings or retaining the slide in Cposition over the ventilating openings, sai means being carried by the frame and having portions thereof extending within the plane of the frame, said portions being concealed by such frame.

4. The eombinationwith a window frame having ventilating openings extendin r there through, of a slide movableover sai openings, said slide having openings corresponding in number and position to the ventilating openings, slide in position over said ventilating openin s, said uides being located on opposite sides of and spaced from said openings, each guide being independent of and similarfin complemental opposing frame, and means for securing the guides to the frames, said means being located within the concealed portion of the guides.

In testimony whereof I aflix my signature in the presence of two witnesses.
